Where can I watch a National Geographic show online or in an app?

You can watch current season episodes on NationalGeographic.com, the Nat Geo TV app and the FOX NOW app and signing in with a participating TV provider is required. When available, past seasons of shows are unlocked and do not require signing in with a TV provider. For new shows, available episodes are unlocked and a TV provider is not required 60 days after the season concludes.
